Neurotologic Skull Base Surgery T2 CURRENT Diagnosis & Treatment in Otolaryngology—Head & Neck Surgery, 3e YR 2012 FD 2012 PB The McGraw-Hill Companies PP New York, NY SN 978-0-07-162439-8 LK accessmedicine.mhmedical.com/content.aspx?aid=55773108 RD 2024/03/28 AB Although in widespread use, the term “skull base surgery” is somewhat of a misnomer. Only a minority of such procedures are undertaken to expose lesions actually located primarily within the skull base. Most procedures are conducted to expose deep-seated intracranial lesions situated either adjacent to the brainstem (eg, midbrain, pons, or medulla) or beneath the cerebral cortex. Previously, many such tumors were approached via simple openings in the calvaria, which require vigorous and often injurious degrees of brain retraction.
